Method Detail

execute

public <R> CompletableFuture<R> execute(IndexOperation<T,?,?,R> operationToPerform)

Description copied from interface: AsyncMappedIndex

Executes a command that is expected to return a single data item against the database with the context of the specific table and secondary index this object is linked to.

Specified by:

execute in interface AsyncMappedIndex<T>

Type Parameters:

R - The expected return type from the operation. This is typically inferred by the compiler.

Parameters:

operationToPerform - The operation to be performed in the context of the secondary index.

Returns:

A CompletableFuture of the result of the operation being executed. The documentation on the operation itself should have more information.

execute

public <R> SdkPublisher<R> execute(PaginatedIndexOperation<T,?,?,R> operationToPerform)

Description copied from interface: AsyncMappedIndex

Executes a command that is expected to return a paginated list of data items against the database with the context of the specific table and secondary index this object is linked to.

Specified by:

execute in interface AsyncMappedIndex<T>

Type Parameters:

R - The expected return type from the operation. This is typically inferred by the compiler.

Parameters:

operationToPerform - The operation to be performed in the context of the secondary index.

Returns:

An SdkPublisher that will publish successive pages of result data items to any subscriber with demand for them.

mapperExtension

public MapperExtension mapperExtension()

Description copied from interface: AsyncMappedIndex

Gets the MapperExtension associated with this mapped resource.

Specified by:

mapperExtension in interface AsyncMappedIndex<T>

Returns:

The MapperExtension associated with this mapped resource.

tableSchema

public TableSchema<T> tableSchema()

Description copied from interface: AsyncMappedIndex

Gets the TableSchema object that this mapped table was built with.

Specified by:

tableSchema in interface AsyncMappedIndex<T>

Returns:

The TableSchema object for this mapped table.

dynamoDbClient

public DynamoDbAsyncClient dynamoDbClient()

tableName

public String tableName()

Description copied from interface: AsyncMappedIndex

Gets the physical table name that operations performed by this object will be executed against.

Specified by:

tableName in interface AsyncMappedIndex<T>

Returns:

The physical table name.

indexName

public String indexName()

Description copied from interface: AsyncMappedIndex

Gets the physical secondary index name that operations performed by this object will be executed against.

Specified by:

indexName in interface AsyncMappedIndex<T>

Returns:

The physical secondary index name.

keyFrom

public Key keyFrom(T item)

Description copied from interface: AsyncMappedIndex

Creates a Key object from a modelled item. This key can be used in query conditionals and get operations to locate a specific record.

Specified by:

keyFrom in interface AsyncMappedIndex<T>

Parameters:

item - The item to extract the key fields from.

Returns:

A key that has been initialized with the index values extracted from the modelled object.

equals

public boolean equals(Object o)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object
